I use Google Apps email to send out details of a product I sell to people who enquire about it via a web form.
After a month or so I go through my Sent Mail folder and send a follow up email to all those I haven't heard off. Each email is the same except for the person's name in the greeting.
So in summary, periodically I need to send the same email to recipients in my Sent Mail folder that meet certain criteria: I emailed them in the past 2 months, the subject of the email was "My Super Product", I haven't had a reply off them since my last email.
Is there any tool available that can do this automatically?

Gmail filters only act on messages when they arrive. There's not a way to do what you want with filters.
For a pure Gmail solution, you can accomplish almost what you want by judicious use of search and the Canned Responses Lab. That will make sending identical messages to a bunch of people relatively easy.
Another option would be to use some third-party tool. You can get your email via POP3 or IMAP, so virtually any desktop email client can get your messages. There are probably tools out there that will allow you to do what you're looking for. (That's outside the ken of WebApps, though.)
Alternatively, what you really need is a Customer Relationship Management (CRM) solution. Salesforce.com and its ilk probably already have the tools that you want.
